GEORGE E. VAN VORST AND JOHN VAN VORST, OF SCOTIA, NEW YORK.-

ROOFING MACHINE.

Application filed March 19', 1920. Serial No. 367,204.

To all whom it may concern:

Be it known that we, GEoRqE E. VAN

VORST and JOHN VAN VoRs'r, citizens of the United States-of America,residing at S00 tia, county of Schenectady, and State of New York,haveinvented certain new and useful Improvements in Roofing Machines, ofwhich the following is a specification.

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.Similar characters refer to similar parts in the several figurestherein.

This invention relates to machines for ads herently laying upon roofs orthe like, a

covering of roofing-paper or the like.

In covering roofs with roofing-paper, the

commonpractice is to apply to the roofsurface a coating of hot asphaltor tar by means of a mop or swab and then to lay upon the surface thuscoated, strips or sheets of roofing-paper which is usually tarred orwaterproofed.

The principal objects of our invention are to apply the coating ofasphalt or the like to the roof-surface, and lay the roofing; paper orthe like thereupon as a substantially simultaneous operation; and toregulate the coating of asphalt or'the like applied to the roof-surface.

Other objects will appear in connection with the following description.

Fig. 1 of the drawings ls a vertical longitudin'al section ofa.-roofing-ma'chine embodying our invention, the section being taken onthe broken line 1-1 in Fig. 2.

- Fig. 2 is a view in front elevation of the machine.

Fig- 3 is a top plan view of the machine.

Fig. i is a horizontal CI'OSSfSGOiZlOIl of themachine taken on thebroken line 44- in fieferring to the drawings wherein the invention isshown in preferred form, 1 is a tank, adapted to contain a supply, 2, of

heated asphalt, pitch or the like, the tank being provided with a topopening closed by a door, 3, and with a strainer-diaphragm,

4:, adapted to prevent lumps'or solid substances in the asphalt'frompassing to the lower portion of the tank.

The tank preferably tapers downwardly toward a throat-portion, 5, withinwhich is rotatively mounted a feed-roll, 6, supported by a shaft, '4',mounted in the walls of said throat. I

teeth, 8, similar in cross-sectional form to gear-teeth.

Along certain of the grooves between said teeth, 8, the feed-roll, 6, isprovided with a series of cup-like recesses or pockets, 9, arrangedlongitudinally of the groove.

Im med iately below the feed-roll, 6, is a distributing-roll made up ofa series of'disks, 10, arranged side by side and adapted to roll overthe surface, 11, of a roof or the like as the tank, 1, is drawn alongoversaid surface by'means of a handle, 12.

These disks, 10, are formed with peripheral teeth, 13, adapted to meshwith the elongated teeth, 8, onthe feed-roll, 6, whereby as the machineis propelled over the roofsurface', the disks, 10, are caused torollover said surface and to impart a rotatory movement to the feed-roll,

A shaft, 14, mounted in the walls of the throat, 5, passes through anaperture, 15, of considerably larger diameter in the respective disks,10, tending to support the disks toprevent their escape from the throat,5. I

Toothed pinions, 16, rotatively mounted upon the throat, 5, on oppositesides of the roll formed by the disks, 10, serve to engage saidtoothed-disks, one of .said' pinions when the machine is being propelledportion'5, closely encloses the feed-roll, 6,

and also encloses the upper portion of the roll formed by the disks, 10.

This housing is introverted into the angle between the feed-roll, 6, andthe roll formed by the disks, 10, thereby forming with the walls of thethroat-portion, 5. heating-.

chambers, 18, adapted to contain means for maintaining the feed-roll andthe material delivered by the feed-roll in heated condition;

In one of said chambers, 18, I have shown a pipe, 19, forming'a gas oroil burner which may besupplied with fuel in any known manner. In theother of said chambers, 18, I have The paper passes from the roll, 22,over an idle roll, 2 1, and beneath a pressing roll, 25, which isrotatively mounted upon the lower end of a pair of links, 26, the upperends of which are pivotally mounted concentrically with the. idle roll.2%, upon a bracket, 27, which projects rearwardly fromthe tank, 1. v

A. pair of wheels or rollers, 28, are mounted upon brackets, 29,.projecting from the front of the throat-portion, 5, of the tank inposition to engage the roof-surface when the tank is tipped or tiltedforwardly; and they serve as truck-wheels inpropelling the tank fromplace to place and for quickly changing the direction of movement of thetank.

The operation of the machine is as follows:

The machine having been supplied with a roll of roofing-paper, 23,rotatively mounted upon the bracket, 21, and with asupply, 2, of hotasphalt, pitch or the like, is drawn over the roof-surface in thedirection of the arrow, 30, by means of the handle, 12.

As the machine is thus propelled over the roof-surface the disks, 10,roll along said surface in mesh with; the rearward pinion,

16, and cause the feed-roll, 6, to be rotated in mesh with more or lessof said disks, 10.

As the feed-roll, 6, is rotated its upper portion being exposed tothebody, 2, of hot asphalt or pitch the grooves between its teeth, 8,and the pockets, 9, along the bottoms 1 of said grooves become filledwith the hot asphalt or pitch thus carrying from the tank to the disks,10, measured quantities of the liquid contents of the tank, whichquantities are received by the disks, 10, and carried downward to andare deposited upon the roof-surface, 11, thereby applying to saidsurface a coating of asphalt or pitch adapted to adherently unite to theroof-surface the covering paper, 23. I The roll, 25, is of sufficientweight to press the paper, 23, down firmly upon the asphaltcoatedroof-surface.

The openings, 15, in the disks, 10, being substantially larger indiameter than the 'shaft, 14, extending therethrough, the respectivedisks engage the roof-surface independently of each other so that thedisks accommodate themselves to irregularities in the roof-surface, andtend to deliver the asphalt or pitch quite uniformly to the roofsurfacein spite of such inequalities.

The heating mechanism, 19 or 20, may be employed if desired to maintainthe temperature of the asphalt or pitch as it is delivered from thefeed-roll to the distributingroll formed by the disks, 10.

\Vhen it is desired to transport the machine from place to place or toquickly change its direction of movement, the machine is tiltedforwardly upon the wheels or rollers, 28, until the distributing rollformed by the disks, 10, is raisedabove the roofsurface, the wheels orrollers, 28, thus acting in the usual manner of truck-wheels.

The machine is preferably made throughout of metal and particularly thetank, 1, its throat-portion, 5, and the various rolls and pinions sothat the machine can be preheated in a heating oven or chamber ifdesired before being supplied with the heated asphalt or pitch.
